Do you mind when your CD-DVD or Blu-ray gets scratched

I know I do. CD/DVD/Blu-Ray discs are really sensitive to scratching.
Repairing them can be a pain too, and there are several ways to do so, all with varying levels of success.
A commercial disc repair system is the DVD Dr. which I've had a mild level of success with.
A great home system, though, is liberally rubbing non-gel toothpaste (baking soda kind works the best) with a cotton ball on the disc, then rinsing it with water.
